Ok,thanks! Just make the bores in the torque plate about an 1/8" larger than the bore size you are going to be using! This will also give you some wiggle room for future overbores as well.
ps. Its hard to determine the bolt locations in relation to the bore centerlines with just a cylinder head. Since you have access to the CMM,it should make short work of it. I doubt that a Stovebolt has ever been measured so accurately and precisely. I'll be looking for the Y centerline reference,Thanks....
